West Quarry, Mokra, Czech Rep., collection from quadrat I8, lower part of bed 4 (Devonian to of Czech Republic)

Where: Moravia, Czech Republic (49.2° N, 16.8° E: paleocoordinates 17.7° S, 25.3° E)

• coordinate based on political unit

• small collection-level geographic resolution

When: Macocha Formation, Frasnian to Frasnian (382.7 - 358.9 Ma)

• This is quadrant 8, from the lower part of bed 4 and stratigraphic interval I.

• bed-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; intraclastic, shelly/skeletal grainstone and shelly/skeletal, brown rudstone

• 'shallow carbonate ramp with abundant reef dwelling fauna...have the character of reef banks.' 'northern margin of Devonian back-arc or related basins'
• 'biosparite and biosparrudite limestone, in places with pocket-like fillings of micritic sediment. Bioclasts are intensively micritized. In places, there are complicated stromatactises with originally fibrous rims encircling the stachyods.'

Size classes: mesofossils, microfossils

Collection methods: '4 meter squared quadrants were reconstructed from paleo-sea floor fragments.'

Taxonomic list

• 'Abundance is the number of individuals for solitary organisms or the number of colonies for clonal organisms.' Paper also gives occupied area for each taxon, and estimates skeletal mass produced per year and biomass produced per year -- I have reported abundance values.
